Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/169

I executed s3fs-fuse (latest master) with the following command:

/opt/s3fs-fuse/bin/s3fs -f -d bucket /mnt/s3/ -o allow_other,uid=33,noatime,max_stat_cache_size=0

Then on top of s3fs-fuse I mounted a encfs file system:

encfs -f -d --public --extpass="cat /root/password" -o uid=33 /mnt/s3/ /mnt/encfs/

There is a file with path /mnt/encfs/test/file that has 30 KB. I executed the following command:

echo CONTENT > /mnt/encfs/test/file

After this command the file still has 30 KB although it should only have 8 bytes!

root# ls -l /mnt/encfs/test/file
-rw-r--r-- 1 www-data root 29395 Apr 16 15:38 /mnt/encfs/test/file

The output of s3fs-fuse:

Originally created by @delx on GitHub (Apr 16, 2015). Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/169 I executed s3fs-fuse (latest master) with the following command: ``` /opt/s3fs-fuse/bin/s3fs -f -d bucket /mnt/s3/ -o allow_other,uid=33,noatime,max_stat_cache_size=0 ``` Then on top of s3fs-fuse I mounted a encfs file system: ``` encfs -f -d --public --extpass="cat /root/password" -o uid=33 /mnt/s3/ /mnt/encfs/ ``` There is a file with path `/mnt/encfs/test/file` that has 30 KB. I executed the following command: ``` echo CONTENT > /mnt/encfs/test/file ``` **After this command the file still has 30 KB although it should only have 8 bytes!** ``` root# ls -l /mnt/encfs/test/file -rw-r--r-- 1 www-data root 29395 Apr 16 15:38 /mnt/encfs/test/file ``` The output of s3fs-fuse: ``` set_moutpoint_attribute(3530): PROC(uid=0, gid=0) - MountPoint(uid=0, gid=0, mode=40755) s3fs_init(2713): init s3fs_check_service(3070): check services.

s3fs does not support extended attributes that encfs needs -- we could add support via S3 user metadata.

@andrewgaul: Would it be possible to implement dummy functions for the extended attributes in order to make encfs work?

@delx It is correct that @andrewgaul said.
The extended attributes caold be realized by s3fs supports setxattr, getxattr and listxattr of FUSE interface.
Probably, s3fs will make original HTTP header(example: "x-amz-meta-xatt") for each object which is set extended attributes.

I created new branch "xattr" which supported extended attributes FUSE api.
Please try to use and test xattr branch codes.

Thanks in advance for your assistance.

@ggtakec: I tested your new branch. The error can be reproduced exactly as above.

This time I used the following command:

echo test > file

The output of encfs (with -v flag) while executing the echo command:

@ggtakec commented on GitHub (Apr 21, 2015):

After I checked your log, it did not have log which was calling s3fs_setxattr function.
I was hoping that s3fs_setxattr function is called when s3fs made the file.
Because when I tested s3fs with attar and setfattr command, this function was called.
So s3fs_getxattr function was called, your fuse was compiled with HAVE_SETXATTR flag.
Thus I think fuse does not have a problem for this issue.

And I updated codes on xattr branch which are fixed some problem.
If you can, please try to check new codes(xattr branch).

Thanks in advance for your help.

@ggtakec commented on GitHub (Apr 28, 2015):

@delx I have not been solved this issue yet.
But s3fs puts following log by accessing from encfs:

s3fs_getxattr(2903): [path=/file][name=security.capability][value=(nil)][size=0]

So I think we should need to know who(how to) set this extended attribute for the object(file).
I keep to work for solving this issue, please wait a while.
(And please watch #166 too.)

@ggtakec commented on GitHub (May 10, 2015):

@delx I'm sory for replying late.

I tried to reproduce this problem in the first step.
I have prepared the following environment(ubuntu on EC2).

  • ubuntu
$ uname -a
Linux ip-XXX-XX-XX-XXX 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.2 LTS"
  • s3fs
    Use both master branch and xattr branch.
  • encfs
    version 1.7.4 installed by apt

Then I tried to check both master and xattr branch s3fs.
Following command for mounting.

# s3fs <my empty bcket> /mnt/s3 -o allow_other,max_stat_cache_size=0 -f -d &
# encfs -f -d --public --extpass="cat /etc/encfspw" /mnt/s3/ /mnt/enc/ &

Next, I done following.

$ echo CONTENT > /mnt/enc/test/myfile

$ ls -la /mnt/enc/test/myfile
-rw-r--r-- 1 ubuntu ubuntu 8 May 10 04:54 /mnt/enc/test/myfile

$ cat /mnt/enc/test/myfile
CONTENT

$ ls -la /mnt/s3/T9P1ppigtD1,J7wUu8fa3jKR/V57HIrvB6X9JuxAQcwDdlIhP
-rw-r--r-- 1 ubuntu ubuntu 16 May 10 04:54
/mnt/s3/T9P1ppigtD1,J7wUu8fa3jKR/V57HIrvB6X9JuxAQcwDdlIhP

$ cat /mnt/s3/T9P1ppigtD1,J7wUu8fa3jKR/V57HIrvB6X9JuxAQcwDdlIhP
??dYb?A1g??v??

Consequently, I think the cause of this problem is not that s3fs does not support the extended attribute interface.
At first, I was mistaken for the cause of this problem is it.
But in my latest environment(ubuntu), encfs + s3fs are operating without problems now.
I think that the cause of this problem is another factor, however I do not know the cause at the moment.

Regards,
